SELF-LEVELING BERTH.

SPECIFICATION forming part of Letters Patent No. 264,052, dated September 5, 1882.

' Application ined March 11, 1882. (No modela To all whom it may concern Be it known that I, ALBERT AUGUSTUS YOUNG, a citizen ofthe United States, residing at Boston, in the county of' Suffolk and State of Massachusetts, haveinventetl certain new and useful Improvements in Self-Leveling Ships7 Berths; and .I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable -others 1o skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of this invention is lnainly to avoid undue friction upon the pivots or bearings of the main support ot' a seltleveling berth, and as a consequence to permit of free oscillating movement of the berth at any anzo gle the supports of the berth may assume, whether permanently by the disposition of the oscillating beam which constitutes such main support, or temporarily by the rolling or pitching of the vessel; and, secondarily, to provide means for equipoising the berth to ,the person of the occupant. l

My improvements consist in supporting the main oscillating beam upon a cross-head in such manner as to be longitudinally adjustable 3o upon the latter, and in supporting the said cross-head, in turn, adjustably upon its sup-A ports, the object of this being to enable the point of suspension or center of oscillation of the berth to be varied to equipoise the berth 3 5 to the person for the time occupyingit, and to reduce the friction between the beam and its point of oscillation to the lowest possible point.

The drawings accompanying this specification represent, in Figure l, a front view, and

4o in Fig. 2 a plan, of a self-leveling berth containing my improvements, while Fig. 3 is a cross-section of the same. Figs. 4 and 5 represent moditied constructions of the support, and Figs. 6 and 7 modified forms of construction of the set-screws for adjusting the amount of friction on the bearings.

In the above drawings,Arepresents a ships berth or lounge, pivoted at each end to the lower end of an upright hub or bar, b, the upper end of which is secured rigidly to one end 5o of a horizontal oscillating beam, B, which, in the present instance, is an open one, composed ot' two side bars, o c, joined at the ends. The bars c c ot' the beam B extend through a horizontal cross-head, G, and are confined to the latter by set-screws d d, or their equivalents,

by which means the relative positions of the beam and cross-head may be varied longitudinally of such beam. To support the beam B in position, I employ two conical -pointed 6o pivots, which are screws or bolts, e e, passing through the upper part of blocks or car riers D D, such blocks being supported and adapted to slide upon two parallel horizontal bars or guides, E E, which are disposed above the berth A, and are firmly secured at their ends to the walls ofthe state-room or the supports of the berth, whatever they may be, each block D being confined to its bar E by a set-screw o It is very desirable in these self-levelin g ships berths that means should be provided for enabling the balance or equipoise of the berth to be adjusted to the proportions of the occupant. To accomplish this by simply shifting the position of the pivot of the beam is not practicable, as a state-room is not large enough to permit ot' it. Hence it becomes necessary to provide a compound pivot or point of suspension by which the pivot may be changed, 8o while the berth remains stationary. This is readily accomplished by connecting the beam B adjustably to the cross-head C and pivoting the cross-head, in turn, adjustably to the bars E E.

lIt will be obvious that if the cross-head C and beam B be tilted out of a horizontal position, whether, as before stated, permanently or temporarily, by the rolling or pitching of thevessel, the friction upon the pivots c e will 9o be but slightly increased. It will also be seen that but little labor is required to equipoise the berth to the person of the occupant.

A modified construction of the device is' shown in Fig. 4 f the drawings, in which the 95 cross-head O is supported adjustably upon a horizontal bar, h, or two parallel bars, while the beam B is disposed between two ears, t z',

pendent from the cross-head, the pivots e ebeat its ends the suspensoty of the berth A, and ing screwed through the said ears to permit of the blocks I) D, mounted adjustabiy upon the the necessary longitudinal adjustment of the bars E and supporting the pivots e, which in cross-head, a series of pockets being formed turn support the cross-head O, substantiaiiyas 15 in the sides of the cross-beati to receive such described.
